Reports White House May Tighten Limits on Chinese Researchers Alarms Scientists
“It just seems odd that you would again try to restrict by nationality rather than on the basis of any one individual security threat,” said Dr. Atul Grover, executive vice president of the Association of American Medical Colleges. “That’s why we have a security process.” STAT
California State Audit of San Diego’s Hepatitis A Emergency
Assemblyman Todd Gloria is asking the state to determine whether the local response to the region’s deadly hepatitis A outbreak was by the book. The outbreak killed 20 people and sickened almost 600 others last year. Any examination of San Diego’s hepatitis outbreak response will have a national audience with linked cases confirmed in Arizona, Colorado, Kentucky and Utah. San Diego Tribune

CHEMICAL WEAPONS
Critical Care Toxicology: Diagnosis and Management of Critically Poisoned Patient
The specialty of toxicology is at once the oldest and newest specialty of medicine. The development of new drugs on a daily basis; transportation and use of thousands of industrial chemicals; and the potential for terrorist chemical warfare release make it infinitely more complex.

The Light Chain Defines the Duration of Action of Botulinum Toxin Serotype A Subtypes
Botulinum neurotoxins are the most potent protein toxins for humans and potential bioterrorism threats, but they are also widely used as pharmaceuticals. Within the large family of BoNTs, only two subtypes are currently used as pharmaceuticals, with many BoNT subtypes remaining as untapped potential sources for unique pharmaceuticals. mBio
Assessing the Performance of Real-Time Epidemic Forecasts: A Case Study of the 2013-16 Ebola Epidemic
Researchers found that probabilistic calibration was good at short time horizons but deteriorated for long-term forecasts, suggesting that forecasts were of good enough quality to reliably inform decision making only a few weeks ahead of time, reflecting the high level of uncertainty in the processes driving the trajectory of the epidemic. bioRxiv
The Forgotten Ebola Survivors of Sierra Leone
Mariatu Kargbo contracted Ebola while working as a nurse. She survived and is now chairperson of the branch of the Sierra Leone Association of Ebola Survivors (SLAES) in the northern city of Makeni. While grateful to be alive, she says she tires easily and feels weaker than before. NPR
Gain of Function Analysis Reveals Non-Redundant Roles for the Yersinia pestis
Virulence of Yersinia pestis in mammals requires the type III secretion system, which delivers seven effector proteins into the cytoplasm of host cells to undermine immune responses. All seven of these effectors are conserved across Y. pestis strains, but three — YopJ, YopT, and YpkA — are apparently dispensable for virulence. (abstract) bioRxiv
Panels for Testing Diagnostic Tools Targeting the Causative Agent of Melioidosis
Diagnostic tools designed to target Burkholderia pseudomallei, the causative agent of melioidosis that was classified as a Tier 1 Select Agent by the U.S. Centers for Disease Control and Prevention, have typically suffered from false-positive and false-negative results because of a lack of understanding of the genomic diversity of B. pseudomallei and its genetic near neighbors.

Our Decades-Long Search for a Universal Influenza Vaccine Needs a Shot in the Arm
Even now, as Americans begin to put away the thermometers, hand sanitizers and cough drops, researchers are preparing for the next flu season. As early as February, they began trying to predict which influenza strains will dominate so they can create the right cocktail for next season’s vaccine. USA Today
Yemen Braced for Another Cholera Epidemic
Doctors are concerned that the current rainy season – which began in mid-April and usually lasts until the end of August – will trigger another outbreak of the disease, with conservative estimates suggesting that millions of people will be at risk of infection if the disease spreads uninterrupted. The Telegraph
Dengue Fever – Réunion, France: Disease Outbreak News
Although sporadic autochthonous dengue fever cases and clusters have been reported in Réunion before, the upsurge of cases since the beginning of 2018 is unprecedented. A lack of herd immunity in the local population may be enabling further transmission of the virus. Relief Web

MEDICAL COUNTERMEASURES
Even a ‘Bad’ Flu Vaccine Could Save 61,000 Lives: Study
A truly dismal flu vaccine could still save thousands of lives, as long as roughly 40 percent of Americans got their shots, new research suggests. At that coverage level, a vaccine that was only 20 percent effective would avert 21 million infections and almost 130,000 hospitalizations — and save 61,000 lives. US News & World Report
Ukraine’s Momentous Vaccination Effort to Stop Measles Outbreak
Over 12,000 people have been infected with measles in Ukraine so far this year. Of those affected, 9158 have required hospitalization and 9 have died.
